Evaluate shift from branch to digital channel
Business Case: OneMain Credit Card — Branch vs. Digital Acquisition
OneMain operates a credit card business with two primary customer acquisition and servicing channels:
- Traditional (Branch/Local): Customers are acquired and serviced through physical branches.
- Digital: Customers are acquired and serviced via online platforms and mobile applications.
Assume both channels are operational and can be utilized in Year 1.
Q1) Strategy
Explain why OneMain might consider de-emphasizing or entirely exiting the traditional branch channel, shifting investment towards the digital channel. Provide a structured answer covering the following aspects:
- Costs
- Revenue
- Risk
- Customer Experience
- Scalability
- Competitive Dynamics
Q2) Break-even Channel Mix (Unit Economics)
For Year 1, OneMain forecasts a total of 100,000 new card customers. Let p represent the fraction of these customers acquired via the digital channel (consequently, 1 − p will be acquired via the branch channel).
Consider the following simplified per-customer economics:
- Branch Channel
- Revenue: $200
- Variable Cost: $100
- Contribution Margin: $100
- Digital Channel
- Revenue: $200
- Variable Cost: $0
- Contribution Margin: $200
- Fixed Costs (Year 1 Total): $11,000,000 (This covers corporate overhead and channel-specific programs).
Task: Calculate the minimum digital share p (as a percentage) required for OneMain to achieve a break-even profit (profit ≥ 0) in Year 1.
Output:
- The break-even digital share p (as a percentage).
- A clear profit equation used for the calculation.
Q3) Reasonableness Check
If the calculated break-even digital share p is very small (e.g., single digits), how would you interpret this result? What underlying assumptions in the model could potentially make this result misleading?
Q4) How to Increase Digital Share
Assuming the company needs to achieve at least the calculated break-even digital share, propose a comprehensive plan to significantly increase digital adoption among potential customers. Your plan should include:
- Leveraging customer funnel stages (from awareness to application, approval, and activation).
- Strategies for pricing/offers and ideas for referrals/partnerships.
- Specific experiments you would design and the key metrics you would track (including primary metrics and guardrail metrics).
Q5) Risk Implications
Compared to the traditional branch channel, does digital onboarding and servicing typically lead to an increase in fraud risk and/or credit risk?
- Clearly define both fraud risk and credit risk.
- Explain potential mechanisms that could either increase or decrease each type of risk in a digital context.
- Propose relevant monitoring metrics and mitigation strategies (covering product design, model-based controls, and operational processes).

Core dilemma
The central engineering conflict for a Data Scientist is to quantify and manage the multi-dimensional risks and opportunities of a strategic business pivot (channel shift) using data, ensuring the analytical framework is robust enough to guide investment and operational changes while balancing immediate financial gains with long-term risk exposure and customer experience.
